Question

Drawing straight lines on both the surfaces of solids and then pointing the points where they intersect and drawing lines which forms the line of intersection this process of finding the line of intersection is termed as _______ method.

(a) assumption

(b) line

(c) removing material

(d) cutting- plane

I got this question in a job interview.

The doubt is from Intersection of Surfaces topic in section Development & Intersection of Surfaces of Engineering Drawing

Answer 1

Correct choice is (b) line

The best I can explain: A number of lines are drawn on the lateral surface of one of the solids and in the region of the line of intersection. Points of intersection of these lines with the surface of the other solid are then located. These points will obviously lie on the required line of intersection.
